Andrew, at that point just buy a box truck, really just not worth it.
360ccf, if you're relying on DAT alone I feel bad for you, very rarely does an expedited load show up on DAT, there are partials sometimes that will fit, but you are very likely to run into issues, such as the shipper or receiver are wrong about DIMS and it ends up not fitting, or they don't have ramps and cannot load/unload you (ever been to the northeast?). I use DAT and Truckstop mainly when in bad areas trying to get anything for backhaul, sometimes I get lucky, but you can't run a business planning to get lucky, it's just a bonus.
To the OP, with a new MC you will get no loads at first, need to let it age 1 yeay before poeple will work with you.
You can work for someone like Millhouse or Delta as an owner operator in the meantime, learn the business while your MC is aging.
It's far from an ideal place to be in, but it's a start.
